I only take lessons once a month. After each lesson I practice what I've been taught for 4 weeks. After going to the driving range 4-5 days a week and playing 18 holes once a week I have gained the ability to do what I was taught in my lesson consistently. If you go every week you are not giving yourself enough time to practice what he teaches you and when you go back he'll just tell you the same thing.
